X-ray crystal structure of the complex Et–Hg·TpPh2, which is here reported, represents the first case in which the Hg (bonded to an organic R-group and a tripodal N-donor ligand) is tetrahedrally coordinated (with some distortions), instead of being T-shaped. The compound is orthorhombic, space group P 212121 with a=12.966(3) Å, b=16.940(3) Å, and c=18.412(4) Å; V=4044(1) Å3; Z=4; R(Rw)=0.056(0.057).
R–Hg +离子(R = Me,Et,Pr,i -Pr,Ph,p- Tol,苄基,5-Me-噻吩基或二茂铁基)配合物Tp Ph 2(hydrtritris( 3,5-二苯基-1- ħ吡唑-1-基)borato)或TP 4BR(氢化三(4-溴-1- ħ吡唑-1-基)borato)这里报告。通过1 H,13 C和199 Hg NMR光谱的比较显示,配体Tp Ph 2比Tp 4Br更好。Et–Hg·Tp Ph 2复合物的X射线晶体结构此处报道的,是第一种情况,其中Hg(结合到有机R-基团和三脚架N-供体配体上)四面体配位(有些变形),而不是T形。该化合物是正交晶体,空间群P 2 1 2 1 2 1 1,其中a = 12.966(3)Å,b = 16.940(3)Å,c = 18.412(4)Å;V = 4044(1)埃3 ; Z = 4;R(R w)= 0.056(0.057)。
